OK. I am sure you know this, but here goes. This has been commented on several times. Once you get to 80, or 90, or 100, or whatever you are gonna use, note whether you are able to use the closest window on the castle nut. Often you can't. The best approach is to neither loosen to the prev window nor tighten to the next window. Instead, remove the nut and grind slightly on the face of the nut on the SIDE of your grinding wheel. Then re-apply nut and re-torque and see how things line up. This is trial and error, but you will get exact results. It doesn't take much. Good luck

Oh, and be sure to use the specially hardened flat washer up against the hub. If you don't have them they can be ordered or just get grade 8 washers from your local hdwe store. Anything less will not stand up to the forces and the nut will just dig into the soft washer and the washer will continue to deform and your hubs will loosen as a result
